My caterpillar control method on my cabbages is by hand picking, hopefully rubbing out the eggs when threy are laid. Even so, many get missed and fat juicy specemens need  squashing.
Last year I was hand picking when the grandaughter took pity on them. I gave her a jam jar with holes in the lid and cabage leaves for food. A nice little study project to rear some butterflies.

They were well looked after back at her  home , mum even washed out the jar every morning. In time the food supply ran out, they didn't come to see me for more food, they dont normally eat cabbage. A supermarket one was purchased just for the caterpillars. Next day the caterpillars were purple stiff and dead.

Nothing is ever seen alive on supermarket cabbages. Is consuming those poisons not harmfull to us.

That is it, today I have started to demolish my small chicken ark. I had two hens which died of old age. I have kept the ark in case I was to have some more hens later.

How can one do such a natural thing as to keep chickens in a suburban garden in the present climate. If a neighbours child had a slight cold it would be bird flue, caused by my hens.

Just another step towards the plasticisation our the food and the human being.

In the days prior to chemical fertilisers, the soil was given body by the bulky manure added. Natural nitrogen was added by growing clover etc and the ground given a rest. Now you walk across a wheatfield with 5cm wide cracks in a soil that looks like bad concrete.

The excess nitrogen is stored in some crops and hence goes into our bodies. The nitrogen run of goes into our drinking water, yet more nitrogen (fertilizer) is added to drinking water during the cleaning process at the water works.

Cancers of the internal organd on the increase, I wonder why.
